3 - Example Applications [U12 Datasheet]

Example Applications Overview

The LabJack U12 installer contains 9 example applications:

  • LJconfig: Lists all LabJacks connected to the USB and allows the local ID to be set on each.
  • LJcounter: Reads the LabJack counter and provides the current frequency or count.
  • LJfg (Function Generator): Outputs basic waveforms on AO0 (analog output zero).
  • LJlogger: Saves data to disk, writes data to an HTML page on the Internet, and performs various actions (including email) on trigger events.
  • LJscope: Simulates an oscilloscope by reading data from 2 AI channels in burst mode.
  • LJstream: Uses stream mode to read, graph, and write to file, 4 AI channels.
  • LJtest: Runs a sequence of tests on the LabJack itself.
  • LJSHT: Retrieves and records data from 1 or 2 EI-1050 digital temperature/humidity probes.
  • LJSHTmulti: Displays data from up to 20 EI-1050 digital temperature/humidity probes.

The LabVIEW source code for most of these applications is installed in the examples directory.


When loading the "simple example.vi in Labview 2014, there are some subvi's that can't be found like AOUpdate.vi and GetErrorString.vi.
Where can I get them??

Those are in ljackuw.llb.  Since the location can very, you often have to tell LabVIEW where to find that the first time.  See forum topic #84 for information about using the U12 in LabVIEW.
